a toothed disc revolving about a horizontal-axis I and against which the fruitsorvegetables are pressed for shredding, anda'lso -to provide, in

combination therewith, a means for preventing rotation of the vegetables or fruit undergoing the shredding process.

A still further object of my invention is to provide an adjustment whereby the clearance be"- tween the food feeding tube and the teeth of the shredding disc can be finely adjusted to ensure maximum efiiciency.

With the foregoing and other objects in view as shall hereinafter appear, my invention consists of a device as described and illustrated in the accompanying drawings in which- Figure 1 is a side elevational view of my device.

Figure 11 is a side elevational view of the housing supporting plate as shown in Figure 10.

Like characters of reference indicate corresponding parts in the different views of the drawings.

My device comprises a suitable stand 2 having an electric motor 3 mounted on the top thereof. A plate 4 is secured to the stand 2 in front of the motor 3 and has an orifice 5 in alignment with the shaft 6 of the motor. The shaft '6 is threaded at its outer end and protrudes through the orifice 5 in the plate 4 to carry a shredding disc I.

The hmisiiirs: jeeps tits battomitenr videarlis; he-ii eerilica .112.hen athethed sc. the heus is H is formed with a feeding tube I3 which is open at both ends and provided with a centrally located web I4. The feeding tube extends upwardly and outwardly and its inner end is concentric with the toothed plate I and is in close proximity to the crowns of the teeth 8, as shown in Figure 1.

A bracket 15 having an upwardly turned end is secured to the top of the motor 3 and extends therefrom. Such bracket carries an adjusting screw l6 extending therethrough and threaded into the plate 4. By adjusting screw IS the plate 4 and housing H carried thereon can be bent or sprung inwardly or outwardly to a slight degree whereby the clearance between the teeth and the inner end of the tube l3 can be adjusted. Vegetables or fruit are fed into the device through the tube i3 by means of the feeding plunger H, the handle I8 of which is held in the hand of the operator. The plunger is of slightly less diameter than the inside diameter of the tube 13 and is formed with a central slot l9 adapted to receive the web M in the tube when the plunger is inserted into the tube.

When operating my device the motor 3 is set in motion and a receptacle is placed beneath the orifice l2 in the bottom of the housing H. Vegetables or fruit are fed through the tube l3 by means of the plunger l1 and are pressed against the rotating disc I. The teeth 8 on the disc 1 shreds the food which drops downwardly through the orifice l2 into the receptacle. During such operation the web M in the feeding tube l3 acts to prevent the disc 1 from rotationg the food being shredded. Some of the shredded food will pass through orifices 28 formed in the plate 1 by the extruded teeth 8, but will drop from the rear of the plate 1 since no hindrance is oifered due to the spider-like construction of the number 9.

In order to facilitate the removal of the shredding unit I provide a collar 20, which is secured on the motor shaft 6. The collar is formed with an orifice 2| adaptedto receive a rod 22, the length of which is somewhat greater than the distance between the shaft 6 and the adjusting 3 screw l6. When the rod 22 is in position and resting against the adjusting screw 16 as shown in Figure 3 it serves to lock the motor shaft against rotation so that the shredding unit may be unscrewed.

In order that the housing ll may be removed for cleaning purposes, it is provided with two lugs 23 whichcarry studs 24 receivablei'nto open ended slots'25 in lugs 26 which extend from the sides of the plate 4. Wing nuts 21 are threaded upon the studs to engage the rear faces of the lugs 25. As the spider arms 9 are spaced away from the back of the shredding disc I, it can be thoroughly cleaned. v

From the foregoing description it will be apparent that I have devised an eflicient yet simple device for shredding vegetables andfruitaand although I have described a particular embodi ment of my invention it is to be understood that I can make such changes and alterations asI .may from time "to time deem necessary without departing from the spirit of my invention as set forth in the appended claim. What I claim as my invention is: V In a device of the character described, a vertical disc rotatable about a horizontal axis and against which vegetables or fruit are pressed to be shredded, shredding teeth carried by the disc, a housing in whichthe disc is contained and formed with an orifice in its bottom, an open ended feeding tube of substantially the same diameter as the disc protruding upwardly from the housing at an angle and having its inner face adjacent to and concentric with the toothed face of the disc and through which vegetables are fed to bear against the teeth, a dividing web in the tubeto retain the material passing therethrough against; rot'ation,-a feeding plunger adapted to be manually'mbved inwardly through the feeding tube to press food against the shredding disc and having a slot therein in which the feeding tube web is received and whereby the plunger is retained against rotation in the tube, the inner face oi the plunger being in a vertical plane when gin-the tube so that such face is parallel to the face of the vertical disc irrespective of the position of the plunger in the feeding tube.
